They look like '60s hats. I assume the hole in the bottom cymbal was intended to reduce airlock, but its unlikely to make a significant difference and it shouldn't affect the sound. Since '60s hats aren't that valuable to start with, I wouldn't expect the hole in the bottom to affect the value of the pair by much.

Those have a 1960s looking trademark stamp and 1960s lathing. Assuming they are 14", the expected median price is $140 with half selling for between $100 and $185 n=43 completed sales. As with BosLover I wouldn't expect the hole to affect the price very much and would still use the $140 median price as the best estimate. The only thing which would change that is if the hole was drilled to stop some sort of tonal groove crack, but I don't see anything like that in your photos.
